Re: How to measure superheat and subcooling
That is correct.
There are still plenty of antique systems still operating around here and many are only controlled by pressure controls.
Most of the low pressure switches i set for temp control usually need a slight adjustment on the diff to achieve the desired effect.
Doesnt take long to watch it reach cut out. Beats coming back to move the diff slightly at a later date.
It also amazes me how many times you find a system controlled by t/stat that hasn't had the pressure control set up to control the icing of the coil.It seems some people would rather install a defrost timer instead of turning a screw.
